With relationship expert Dr. Mike Dow by his side, Brody proved during his series' debut yesterday that he isn't shy about using his own love life as fodder -- and we ate up every minute of it. Here are the juiciest moments from the Cali stud's mini tell-all:

Brody Jenner's Instagram

He once dated his older brother Brandon's wife, Leah.

"[Brandon and I have] known each other since we were 11 years old; I was 11 years old, he was 13," said Leah, who joined Brody on the podcast. (That's Brody, Brandon, Leah and Brody's girlfriend Kaitlynn Carter in the Instagram photo above.) "We started playing [music] in high school together. I had a boyfriend, he had a girlfriend. And then when I was single one day, he was single one day, and he came up to me and he's like, 'I've been in love with you since you were 11 years old.'"

But wait for it...

"The boyfriend at the time was me," Brody interrupted. "That's what made it really awkward."

"So [Brody] was my boyfriend in the fifth grade...[but] we never kissed," Leah said.

And no, it's not because his girlfriend wasn't invited. "Realistically, I had work commitments and it was a long way away," he explained. "It's not like it was right down the street, so that made it a little bit more difficult. I wished Kim the best, and she hit me back. I told her I wouldn't be able to attend and she had no problem with it, and I think that that is all that matters."

His number is 12...allegedly.

"You tried to throw out a 12, but we know it's not a 12." Dr. Dow said.

"Twelve times a number," Brody admitted with a chuckle, before adding, "I lost count."

His first kiss with girlfriend Kaitlynn was a little...messy.

"I was pretty inebriated," Brody confessed. The lip lock happened at a Halloween party; he was wearing white face paint for the Día de Muertos-themed bash and she was dressed as a unicorn. "I felt a little uncomfortable kissing her because the next thing you know, once we did, she had white stuff all over her face," Brody said. "It wasn't the most beautiful thing in the world, but she was great."

Indeed, the couple are still going strong. He captioned the photo above, "Love this woman."
